Adam Muema ran for two touchdowns and Everett Beed returned a fumble 52 yards for a score, leading San Diego State to a 28-9 win over Air Force on Saturday.
San Diego State (8-3, 6-1 Mountain West) ran its winning streak to six as it reached eight victories for the third consecutive season.
Muema, who scored on runs of 20 and 15 yards, rushed for 81 yards on 15 carries as the Aztecs gained 178 yards on the ground. Walter Kazee added 106 yards on 23 rushes.
Air Force (5-5, 4-2) could not overcome three turnovers by quarterback Connor Dietz that led to three San Diego State touchdowns.
Beed's 52-yard TD came after he picked up a loose ball when Dietz had the ball slip out of his hand as he brought it back to pass. The score put the Aztecs up 21-3 early in the third quarter.
Dietz fumbled twice and threw an interception. Air Force had four turnovers.
The Aztecs have converted 17 of their opponents' last 19 turnovers into points.
The Falcons were able to move the ball, gaining 393 yards in total offense, including 320 on the ground. But Air Force could not sustain drives despite converting on 6 of 9 fourth-down plays.
Parker Herrington kicked a 22-yard field goal on the Falcons' first possession but also missed a 42-yard attempt at the end of the first half.
San Diego State gained only 268 yards in offense as it employed a conservative, ground-oriented approach. Quarterback Adam Dingwell was 11 of 18 passing for 90 yards, including a 2-yard touchdown to Chad Young.
Wes Cobb scored on a 5-yard run late in the third quarter for Air Force to cut the lead to 28-9.
The last time San Diego State won at least eight games in three consecutive seasons was from 1972-77.
San Diego State remains in the hunt for its first Mountain West title in its last season in the conference. The Aztecs are scheduled to move into the Big East in football next season
